I recently took it upon myself to read Charles Taliaferro and Stewart Goetz‘s work Naturalism (for sale here).  I highly recommend the book for anyone looking for a good summary of some considerations of modern philosophy on the topic of naturalism.  The work is pithy, cogent, and I think easy to follow even for those not well-versed in the technical jargon and historic arguments surrounding this traditional metaphysical debate.  I would caution, though, that I think that the book seems to me overly critical of some features of naturalism, and also to me seems to overgeneralize many characteristics which I think abound in naturalists and non-naturalists alike.

I had the great pleasure of being introduced to Taliaferro last fall, and will likely be meet him again in a few days, so I took the time to throw together a little gut-reaction response to the work Natualism (which, I rather think might be better titled “Against Naturalism”, which indicates better that the purpose of this book seems to be the construction of an argument against naturalism, rather than some merely informational and “objective” presentation of historic facts and debates).

Here is my response to their work (in either ogg vorbis or mp3 format).

If you don’t feel like taking the 15 minutes to listen, here’s the gist of my thoughts, without most of the explanatory substance:

1. Yes, I agree with Goetz and Taliaferro that naturalism as they characterize it (through examples) stands on shaky ground, but…
2. Naturalist perspectives, being based on the ever-expanding realm of scientific advancement, are not simply reductionist.  Rather, their role can expand as our empirical observations and theories about these observations expand.  My feelings on this follow from my (mildly Kuhnian, i think) view that science is a primarily pragmatic rather than epistemological endeavor.
3. Because science offers us the opportunity to challenge traditional “supernatural” explanations, it bears the possibility to act as a corrective check for, or at least calls us to critically reflect upon, our folk psychology/physics/philosophy/metaphysics/dogmas.
4. Finally, I think that a strict, parsimonious, positive naturalism is not just likely epistemically problematic–it is psychologically untenable even for its most outspoken adherence (but so is anti-naturalism in some ways).  In the long run, though, if the apparent choice is between accepting on or the other tradtional dogma (either naturalist or unnaturalist), I would just assume have both perspectives around as long as possible duking it out, as neither seems wholy cogent to me.  With the argument preserved, we can pragmatically utilize one assumption in one context generally (say, anti-naturalism for religion; naturalism for science), but allow these perspectives to challenge each other in their own contexts as well.  In this way, I hope we can either realize that these distinctions are irrelevant, or that they are somehow complimentary, or that some better alternatives exist instead–and enjoy the fruits of continued argument.

What struck me as interesting, was that when I was looking for some alternative perspectives on naturalism while writing my response, one of the first results provided by my friend Google was lil’ ol me.  Yes, on the first page of my google results was an entry that I posted in October last year, entitled “Hobbes and Modern Science v. Descartes“.  Back in October, though, I was sort of on the other side of the argument.  Back then, I was chastizing modern science for its naturalist assumptions, rather than lauding it for bringing options to the table–at least until the end of the article.  In the end, though, it seems that both today and last october, I was arguing from one side (first against naturalists, then against anti-naturalists) in order to get to the middle.  In both places, I criticized dogmatism, dualism, and hubristic assumptions that we already know what types of substances make up the entirety of the cosmos.

The major discrepancy between my old article and my new one, it seems to me, is that I was content to characterize science in my October post as presuming the sort of materialistic naturalism that Goetz and Taliaferro seem to see in it, but this week I argued that that view of science is short-sighted.  Which description is more accurate?  In a way, I think both.  I think the end paragraph of my recorded response hints at the answer.  It seems that real human beings simply don’t portray stable, context independent dispositions of this sort.  In one context, we might all predictably be naturalists (say, when you consider whether or not you should worry about a 1,000 anvil falling on you from above), and in others we may all be anti-naturalists (say, when considering our plans for the future or interpreting our emotions).  It may simply not be possible to separate these two categories in a way that is both meaningful and able to be held by a real person over time.

Also, if you’re in the Sioux Falls area, I heartily implore you to come to Charles Taliaferro’s talk at the Augustana Naturalism Symposium this week; it will make your life better.

Also, I tried to stream my recorded response to Naturalism, but it does not seem to work for me.  Try it, if it shows up for you:

The cause of Sense, is the Externall Body, or Object, which
presseth the organ proper to each Sense, either immediatly,
as in the Tast and Touch; or mediately, as in Seeing, Hearing,
and Smelling: which pressure, by the mediation of Nerves, and other
strings, and membranes of the body, continued inwards to the Brain,
and Heart, causeth there a resistance, or counter-pressure,
or endeavour of the heart, to deliver it self: which endeavour
because Outward, seemeth to be some matter without.  And this Seeming,
or Fancy, is that which men call sense; and consisteth, as to the Eye,
in a Light, or Colour Figured; To the Eare, in a Sound; To the Nostrill,
in an Odour; To the Tongue and Palat, in a Savour; and to the rest
of the body, in Heat, Cold, Hardnesse, Softnesse, and such other qualities,
as we discern by Feeling.  All which qualities called Sensible,
are in the object that causeth them, but so many several motions
of the matter, by which it presseth our organs diversly.  Neither in
us that are pressed, are they anything els, but divers motions;
(for motion, produceth nothing but motion.)  But their apparence to
us is Fancy, the same waking, that dreaming.  And as pressing, rubbing,
or striking the Eye, makes us fancy a light; and pressing the Eare,
produceth a dinne; so do the bodies also we see, or hear, produce
the same by their strong, though unobserved action

The absurdity, to me, was not merely that Hobbes thought that he had figured out the mechanisms that ruled over our senses and feelings simply by expanding simple principles of interaction of bodies.  Rather, I laughed because I thought it was preposterous that Hobbes thought to account for non-physical things, like emotions and mental activity, by means of materialist mumbo-jumbo.

Curiously, I was simultaneously quite sincerely open to, if not entirely credulous of, the findings of modern psychological studies which played the exact same role–namely, making the naturalist presumption that those things which seem incorporeal (like thoughts, sensory data, and emotions) could be studied as causes of simple physical interactions observable, for instance, by means tools like nMRI.  Modern naturalist science (I’m convinced that naturalism is not in any way definitional of science, but rather a mere ubiquitous presumption of modern scientists and the in-vogue scientific paradigms) simply has a more complex version of Hobbes’ materialism.  Rather than simply positing that something “preseth on the eye”, biologists a conception of our senses as the products of a complex of chemical and physical interactions which can all be reduced, theoretically, to a naturalistic incarnation of particle physics.

Each of these two perspectives–Hobbesian materialism and modern naturalist science–has issues with the classical Cartesian mind/body dualism.  What I considered incredible in the Hobbesian perspective, I should recall, is not the given dualism ” between two sorts of ‘stuff’, material and immaterial” (as Rorty calls it), but was once an idea marked more by its novelty than its broad acceptance.  With what reasons did dualism replace materialism as the dominant metaphysical structural assumption?  Certainly a number of enticing dualist metaphysical systems exist, and we might have good reason/s–logical or practical–to accept any of these.  I am not convinced that this dualism is essentially reasonable (or for that matter, if it is, that it is reasonable that we should assume that the non-material side of this dualism should have laws similar to our empirically-derived laws for the natural world); I am likewise not convinced that the material dualism has any cogent appeal over metaphysical tri-ism, quad-ism, or infinit-isms (do metaphysicians have terms for these?), other than theoretical parsimony.

Rorty speaketh

Richard Rorty opens Philosophy and the Mirror of Nature, Chapter 1 with this to say about dualism:

Discussions in the philosophy of mind usually start off by assuming that everybody has always known how to divide the world into the mental and the physical–that this distinction is common-sensical and intuitive, even if that between two sorts of “stuff”, material and immaterial, is  philosophical and baffling”

While I don’t think that this position is completely fair or accurate, Rorty’s point is well-made.  If we need a dozen or more metaphysical systems for bridging that “between” in the mind/body dualism–epiphenominalism, parallelism, occasionalism, and their ilk–and the whole dualist project is so difficult for us to fine-tune, what makes this dualism seem so obvious?  I suspect Rorty is not just being eristic when he implies that its our dogmatic entrenchment which makes this dualism seem natural, not some objectively-apparent metaphysical substructure.  This dogmatic entrenchment, I think, is what made Hobbes’ materialist metaphysics seem so quaint and rediculous; meanwhile, my dogmatic entrenchment in the authority of modern scientific findings allowed me to provisionally accept a sort of materialist perspective.  Perhaps it is unfair of me to so readily accept one while simultaneously poo-poo-ing the other.

I enjoy Rorty’s criticism of this dualism, but I think my position is still largely gauche to his.  We should not ignore the predominant metaphysical assumption of dualism–nor, conversely, the metaphysical (or physical) presumption of monism/materialism (or other metaphysical -isms).  We simply ought to be aware of, but not necessarily strictly opposed to, our dogmatic assumptions.  Likewise, we should take note when our various presumptions do not jibe well.  Do we assume dualism, yet affirm the findings of research that presumes or requires monism?  If so, is it merely the result of the brute cultural force of one over the other, or are there good reasons for believing both?  Certainly we might simply mean “monism” and “dualism” in different ways.  Dualisms, of course, may be distinctions between “subtances”, “properties”, or “predicates”, among other things; or perhaps it is fair of us to utilize dualist assumptions in a monist reality or monist assumptions in a dualist reality, if they get us the practical results we desire in some parsimonious way in some areas.  In the same way that we still utilize Newton’s laws for some gravity calculations, despite the existence of more precise post-Einstein calculations, it may simply be the best to use one or the other as a tool.  By this point you surely have figured out that this is my pragmatic proposition for an approach to metaphysics; It is my belief that a “dualism assumption awareness” campaign is much more likely to give us the results we desire than a “dualist-smashing” campaign which it seems to me Rorty is using to get us to agree to presume materialism for pragmatic purposes (corrections/comments greatly appreciated!).
